How do you get a tyre back onto the wheel?

Tim M · 21 April 2009, 10:02

I have a flat tyre on a trailer. I've had this before and always taken it to a professional to sort but wondered if its possible to get it blown up again on the wheel without any sort of special kit. Past attempts have always failed! So, how do you inflate a flat tubeless tyre? (My problem has always been getting a seal between the tyre and the rim)

Provided that there's no puncture in the tyre then you can blow the tyre back on with a compressor. It often helps to bash the sidewall of the tyre with a rubber mallet to try and get it to seal
If you're brave then you can try this:

putting some liquid soap on the sealing part of the rim helps to bed it down right and seal it ,also make sure the tyre is central on the rim before full inflation ,you can gauge that with the rubber moulding lines running around on the wall of the tyre . if you are trying to get an airtight seal in the first place ,a loop of rope around the tread tightend sometimes helps .

This bloke makes it look so easy - changing big tyres the old fashioned way - looks much easier leaving the rim on.

if struggling to get it to start inflating,
put a ratchet strap around the centre of tyre and tighten it which in turn pushes the side walls out to the rim of the wheel, or easyest route fit a tube in it

used to hate fitting quad tyres,, ratchet strap worked every time also removing the valve insert gets the air in there quicker till its seated, then fit insert and inflate as req

Thanks for the tips. Watched a load of youtube videos on it. Took the easy option in the end and located a spare wheel

i would like to see him with a truck tyre and cross ply with inner tube and a split rim ,get it wrong and the lock ring flyes off and kills you when you pressure it .

But you gotta hand it to the dude, he did in 5 minutes what takes me almost half an hour on a good day !! And infact its such grief I usually just go down to the tyre shop, but I think he's kidding us a bit .. you try breaking a bead on one of those with one smack

Aye right !

I used to fit 66" flotation tyres and other large industrial and agricultural tyres that had been shipped to UK in ISO containers. They were very distorted when they came out as they had usually been packed into the container using a forktruck as a battering ram.
To fit the tyres to a bead (spilt or solid rim) we used to use overinflated (fat) motorcycle or bicycle inner tubes to bridge the gap between the bead and the tyre as we inflated. As the tyre started to fill and grip the rim the tube was drawn out by 'rolling' outwards and working round the rim until the inner tube popped out and the bead sealed. The tyre could then be inflated fully and they always came back into shape. The trick was to use plenty of tyre soap.
There were often little suprises left in the tyres by our jovial foreign friends however we could never retaliate as the shipping only went one way.
Happy days....

This really works, but be VERY careful, it can be VERY dangerous!

balancing ballast

We use bin bags some times, if the rim is not good .. they work well and as there is no weight in them, no need to remove

We have a bead blaster at work - 25L air tank with a 2 inch pipe coming out of it and a twist to open valve - charge to 150psi on the compressor, stick fitting against edge of rim, twist valve and booooooofffff done

Bloody good for dusting in awkward corners too

I can't say I have ever had too many problems seating tyres with a normal 100psi workshop compressor, take the valve core out as suggested. Narrow tyres on relatively wide rims are the worst combination.
